Historically, patents are not just abstract concepts, for they have played an invaluable and practical role in everyday life of the common masses, at large. By rewarding ideas, patents encourage the development of innovations and new technologies in every field. As pointed out by the WIPO, innovation knows no bounds and thus, a patent idea can only be limited by the human imagination ! Here is a record of the weirdest and the most transmogrifying patent ideas throughout the modern-day history.
Ladder-gripping attachment for shoes
Hanging upside down can be a fun activity. It may even make you feel like a kid again, especially if you try it out on the monkey bars. But some adults today are practicing hanging upside down for another reason. Inversion therapy is a form of physical therapy that may help with back pain. The goal is to hang upside down and stretch out the spine! Invented by Edmond Dennis, the “upside down hanging shoes” apparatus (Patent application number US1059284A) makes it possible to stand on a ladder or other support “even when the body of the wearer is inverted and extended downward from the support”. This invention enables the wearer to stand upon a ladder or other support with his body inclined in an imbalanced position and to retain the same.
